Controller with quick link connection developed specifically to execute refrigeration functions. With just two quick link connectors, its installation is simpler and more practical, facilitating the installer’s work. It has three recipe options, each with its desired control temperature (setpoint) and its differentials (hysteresis). It also has specific keys to activate/deactivate the economic mode and turn on/off the light. It also has digital filters, which simulate a higher mass load in the environment sensor (S1), delay the response time (thermal inertia), and avoid unnecessary compressor actions. It includes an intelligent function blockage system and a control function turn-off mode.
